The results of bactericidal and disinfection activity of «Biolok» solutions in laboratory conditions are presented. The research was carried out on test surfaces made of stainless steel, tile and metlakh tiles, wood and concrete. As test cultures were used museum cultures of Escherichia coli (1257 strain), Staphylococcus aureus (209-P strain), mycobacteria (B-5 strain) and Bac. cereus (96 strain). In the course of experiments, disinfection modes (concentration, exposure, and consumption of the solution) were established for disinfection of smooth and rough surfaces. At the same time, it was found that effective disinfection of test surfaces of all types contaminated with E. coli and S. aureus, when treated with a 3.0% solution, at the rate of 0.5 l/m2, respectively, for 1 and 3 hours of exposure. For disinfection the test surfaces contaminated with mycobacteria, it was necessary to irrigate with 5.0% solution of «Biolok» twice with an interval of 1 hour, with an exposure of 24 hours, at the rate of 0.5 l/m2, for each irrigation.

The article presents the results of laboratory and production tests of a new domestic composite preparation «Biolok» (manufactured by «Biosfera»). Laboratory studies were carried out on smooth and rough surfaces. Museum cultures of E. coli (stream 1257), Staphylococcus aurous (stream 209 Р), Mycobacteria (stream B 5), B. cereus (stream 96) were used as test microorganisms. Inactivated horse blood serum was taken to simulate the natural contamination of the surfaces. Production tests were carried out at the objects of veterinary supervision in the Republic Dagestan. As a result of the test, it was found that Biolok has antimicrobial activity and can be recommended for preventive and forced disinfection in case of infectious diseases of farm animals and poiltry.

The article describes the results of laboratory tests of the effectiveness of the disinfectant Monochloride (Iodine chloride) 2%. Laboratory studies were carried out on test objects and test surfaces contaminated with test cultures of microorganisms, which included museum cultures of E. coli (E. coli 1257), S. aureus 209-P, mycobacteria (pcs. B5), and spores (B. cereus pieces. 96). Disinfection of test objects was carried out by the method of irrigation at a consumption rate of 0,25...0,3 l/ m2 with disinfection of smooth surfaces and 0,5 l/m2, with disinfection of rough surfaces. The treatment was performed twice with an interval of 60 minutes. Our work established that the Monochloride (Iodine chloride) 2% has a high disinfectant activity against Escherichia coli, Staphylococcus aureus, mycobacteria and spores. On the basis of the laboratory work, this tool can be recommended for production tests at veterinary surveillance facilities.

The results of field tests of the effectiveness of the disinfectant «Chlortab» for disinfection of objects of veterinary supervision. The test results show that the tool «Chlortab» is an effective disinfectant and can be recommended for preventive and forced disinfection at the sites of veterinary supervision in the control of its quality for the isolation of bacteria of the group of E. coli and staphylococci, as well as forced disinfection in infectious diseases of bacterial (including tuberculosis) and viral etiology, particularly dangerous infections (anthrax and other spore infections).
